How do we earn Waves Community Tokens? Can we sell them?

You have to buy some waves and keep that in your waves lite client wallet. On 15th of every month, you will receive WCT in the same wallet.
Is the amount of wct we receive the same as the number of waves we save?
If I'm not mistaken, it is just the percentage of the amount of Waves you have within your lite wallet before the 15th of every month. I don't know what is the exact percentage but I'm pretty sure that it is not the same amount of your Waves. You can still receive WCT even if you're leasing your Waves. For more information, it is better to join their slack channel and ask the people there.

I did not find their slack channels. Whether you can help me or give them a slack channel link.
